Torx T-15 screwdriver
●
Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)
●
●
Phillips #2 screwdriver
●

Screws
The screws used in the computer are not interchangeable. They may have standard or metric threads and may
be of different lengths. If an incorrect screw is used during the reassembly process, it can damage the unit. HP
strongly recommends that all screws removed during disassembly be kept with the part that was removed, then
returned to their proper locations.
CAUTION:
Metric screws have a black finish. U.S. screws have a silver finish and are used on hard drives only.
CAUTION:
As each subassembly is removed from the computer, it should be placed away from the work area to
prevent damage.
Cables and connectors
Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care to avoid
damage. Apply only the tension required to seat or unseat the cables during insertion or removal from
the connector. Handle cables by the connector whenever possible. In all cases, avoid bending or twisting
